Choose one hardwood tree and one softwood tree from your home country or from North America using this Wood Finder Database E. • C. Provide the correct values where decimal points are involved, e.g. “.45” means 0.45, nat 45.

English Question

We have spent the last lesson learning about the mechanical properties of wood. Prior to that we talked about growth rings and extractives. All of this makes a difference when choosing lumber for various projects.

To give you a break from writing, we modified the format for this reflection. This reflection is aimed at familiarizing you with the technical terms of wood and also the process of finding such information for a specific wood type/group. Choose one hardwood tree and one softwood tree from your home country or from North America using this Wood Finder Database E. • C.

Using information from the database on the two wood types that you chose, provide as with a table like the one below.

• Be sure to include the correct units for the quantities that you enter (if their values have a unit), e.g., for modulus of elasticity and crushing strength.
• Provide the correct values where decimal points are involved, e.g. “.45” means 0.45, nat 45.
• In addition, include photos of the standing trees that supply the two selected wood types. You may/will have to go to other web sources for the tree photos (provide titles xid web links).

NOTE

• To relate to what we learned in the lesson, crushing strength is another name for compression strength parallel to (or along) wood grain.
• Similarity score will be high — stress not — but everyone must find, on their OWN, values for the required properties using the provided source (plus additional sources for pictures).
